Log:
Revert r216080 so kmem_map is capped at 3/5 of the currently rather modest
kernel address space in order to leave space for the buffer cache, pipes,
thread stacks, etc on machines with more physical memory until we take
advantage of ASI_ATOMIC_QUAD_LDD_PHYS on CPUs providing it so we don't need
to lock the kernel TSB pages into the dTLB, basically making the entire
64-bit kernel address space available on relevant machines.

Thanks!
